Description

Technical Field

[0001] The utility model relates to a detection instrument, in particular to an annular sealing strip length detection instrument. Background Art

[0002] Currently, the sealing strips used on vehicles are all made of rubber. Since rubber itself is affected by factors such as temperature and has great elasticity, manufacturers need to repeatedly check the length of the sealing strips before assembly to ensure the quality of assembly. The sealing strips used in many parts of vehicles, such as doors, windows, and trunks, are all annular in structure. When measuring, the sealing strips must be cut off and the length must be measured with a tape measure, which not only causes a lot of waste, but also the measurement accuracy cannot be guaranteed. Utility Model Content

[0003] In order to solve the above problems, the utility model proposes an annular sealing strip length detection instrument with high detection efficiency and high detection accuracy.

[0004] The technical solution of this utility model:

[0005] A ring-shaped sealing strip length detection instrument, comprising a frame and a plurality of detection mechanisms mounted on the frame; the detection mechanisms comprising a technical wheel, a supporting roller, a profiling wheel, and a scanner; the technical wheel and the supporting roller are mounted on the frame, the two are arranged side by side, one in front and one behind; the profiling wheel is mounted above the supporting roller, and moves relative to the supporting roller; a position between the technical wheel and the supporting roller is a detection position; the scanner is mounted above the detection position; and the supporting roller is a driving wheel;

[0006] An annular sealing strip with a white line drawn on it is placed on the technical wheel and the supporting roller and is partially in the detection position. The profiling wheel moves relative to the supporting roller and compacts the annular sealing strip. The supporting roller rotates, driving the annular sealing strip to rotate. As the annular sealing strip rotates, the white line on the annular sealing strip passes through the detection position. The scanner measures the length of the annular sealing strip by detecting the white line on the annular sealing strip. The length of the annular sealing strip is measured starting from the first time the scanner detects the white line on the sealing strip and ending with the second time the scanner detects the white line on the sealing strip. During the whole process, the annular sealing strip is not affected by tension, and the measurement efficiency and accuracy are high.

[0007] The detection mechanism also includes a positioning block, which is installed above the technical wheel and moves relative to the technical wheel;

[0008] When the annular sealing strip is placed on the technical wheel and the supporting roller and is partially in the detection position, the positioning block moves relative to the technical wheel and presses on the annular sealing strip to prevent the annular sealing strip from deviating during rotation.

[0009] The outer peripheral surface of the supporting roller is a toothed surface, on which an arc-shaped annular groove is arranged to accommodate the annular sealing strip; the annular sealing strip is effectively driven to rotate, while the annular sealing strip is not excessively squeezed to cause deformation and stretching of the annular sealing strip, thereby improving the measurement accuracy.

[0010] The detection mechanism also includes an upper template and a lower template. The lower template is installed on the frame. The upper template is installed on the lower template and is molded with the lower template to form a channel for accommodating the passage of the annular sealing strip. The upper template and the lower template are located between the profiling wheel and the supporting roller. The upper template is provided with a hole for avoiding the profiling wheel, and the lower template is provided with a hole for accommodating the upper part of the supporting roller to extend. A guide block is installed at the channel opening.

[0011] The annular sealing strip is placed on the technical wheel and the supporting roller and when the part is in the detection position, the annular sealing strip is placed in the channel.

[0012] The detection mechanism also includes a placement box, which is installed on the frame and has an opening on the top. The supporting rollers are located in the placement box, and the lower template constitutes the cover of the placement box.

[0013] The detection mechanism also includes two positioning wheels, which are mounted on the frame, and the two positioning wheels are arranged side by side with the technical wheel and the supporting roller, one of which is located in front of the technical wheel and the other is located behind the supporting roller;

[0014] The annular sealing strip is placed on the technical wheel and the supporting roller, and when the part is in the detection position, the annular sealing strip is also placed on the two positioning wheels.

[0015] A slide block I is installed on the frame, and a positioning block is fixedly connected to the slide block I;

[0016] The positioning block falls naturally together with the slider I under the dead weight of the positioning block and the slider I, and is pressed on the annular sealing strip.

[0017] A fixed seat is installed on the frame, a slider II is installed on the fixed seat, and an adjusting bolt is also installed on the fixed seat. The adjusting bolt and the slider II drive the slider II to move up and down. The contour wheel is installed on the slider II and moves up and down with the slider II.

[0018] The detection mechanism also includes a display screen connected to a scanner. Preferably, the display screen has the function of judging whether the annular sealing strip is qualified and giving an alarm, specifically by setting a maximum length and a minimum length. If the measured length of the annular sealing strip falls within this range, it is qualified, and if it falls outside this range, it is unqualified.

[0019] Each testing mechanism shares a display screen. BRIEF DESCRIPTION OF THE DRAWINGS
